lM PROVEM ENT IN PLOWS.

Specification forming part of Letters Patent No. 39,536, dated August 11353- To all whom it may concern:

Be it known that I, GEORGE W. N. Yos'r, 0t Nashville, Davidson county,State otTenncssee, have invented certain new and useful Improvements inFlows; and [do hereby declare that the following is a full and exactdescription thereof, reference being had to the accompanying drawings,and to the letters ofreference marked thereon.

In the drawings,Figur-e 1, is a sideview with small plow in front. Fig.2 is a side view with large plow in front. Fig. 3 shows one of thestandard-holders. Fig. 4 shows the standard and cutter combined. Fig. 5shows the standard without cutter.

To enable others to make and use myiuven tion, I will describe itsconstruction and operation.

In the drawings, G indicates the beam of the plow. A and B are thewrought-iron stamiard-holders. These standard-holders are made ofplateiron, and have right-angled angleirons a b attached with rivets, orby Welding, as is clearly shown in Fig. 3. Their contiguous ends lap, asshown at 0, Figs. 1 and 2. The sockets are both on the same side of thebeam, and are secured to it by the same screwbolt (I, that holds thehandles to the beam. This bolt d passes through slots 6 in the sockets.The other ends of the standard holders are secured by the square staples0,'one leg of which passes through a hole,s, while the other plays in aslot, f. The object of these slots is to allow the sockets to beadjustable up or down, so as to give moieor less inclination to theplow-standards. The angle-irons I) serve to brace the sockets againstthe upper and under edges of the beam. D E indicate theplowstandards.These standards are made of wood, with afacing, F, (on thelandside,) ofsheetor bar iron, for the purpose of preventing the rapid wearing awayof the wood by the trio tion against the soil. The front edge of thestandard is protected by the plow. The bar or facing F may be sharpenedso as to form a cutter, as shown on the standard D of the small plow.The standards are secured to the beam by placing them in the sockets A Band then fastening them in the desired position by tightening the nutson the staples o.

It will be seen that I can readily exchange the plows. With the smallplow in front it does good work and leaves the surface in excellentorder. With the large plow in front it thoroughly loosens up the subsoiland leaves itin the furrow opened by the front plow, anti not on thesurface.

Having thus fully described the construction and operation of myinventiomwhat Iclaim as new, and desire to secure by Letters Patent, 1s

1. The wronght-iron standard-holders A B, constructed and arranged asdesct i-bed, in combination with the beam 0.

2. The combination and arrangement of the o. w. s. YOST,
